EFICE SPREAD SHEET Herbert G. Davis, Bronxville, N. Y., assignor to The McBee Company, Athens, Ohio, 2. corporation This invention rel-ates toa spread sheet.

It is an object of the invention to provide a spread sheet comprising a plurality of interlocked, telescoping component sheets (which may be printed and/or ruled as desired and upon which information of any desired sort may be placed), such spread sheets being of simple construction and easy to assemble.

t is a further object of the invention to provide a spread sheet component which is easily fabricated and which involves no wastage of material in its fabrication.

These and other objects of the invention will be apparent from the ensuing description and the appended claims.

One form which the invention may assume is: exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. l is a plan view of the component sheet of the spread sheet of the invention.

Fig. 2 is a plan view of the spread sheet itself.

Referring now to the drawings, the component sheet is designated as Ill and the spread sheet, comprising an assembly of component sheets [0, is designated as H. The component sheet is illustrated as being rectangular in shape and as being scored at l2 to provide a flap l3 which may be folded back against the body portion [4 of the component sheet. The flap I3 is cut parallel to the end of the sheet to provide a slit I5 for a purpose described hereinafter. The body portion it of the component sheet is cut adjacent the score line I2 toprovide a transverse slit [6 and two longitudinal slits 17. A tab I8 is thus formed. 7

In assembling the component sheets thus. described, the flap 13 of each component sheet is folded back against the rear surface of the body portion l4, and the tab [8 of each sheet In (except the upper one) is inserted in the slit 15 of the next overlying sheet. A tape 19, such as Scotch tape or any other suitable adhesive-coated tape, is applied to the tab in the manner illustrated in Fig. 2 so as to lock the tab IS in the companion slit 15. Each tab I8 is free to shift in its slit I5, thus allowing spreading of the sheet in the manner illustrated in Fig. 2. When so desired, the component sheets may be telescoped into compact form, as for storage.

It is thus apparent that a spread sheet and a component sheet therefor have been provided which fulfill the objects hereinabove stated. Thus, the only operations necessary in fabrication of the component sheet, other than cutting 5 out a blank of the proper shape and size, are the following: The score line -l2 is formed and the sheet is cut at only two places. The only operations involved in assembling the sheets consist of folding the flaps l3, inserting the tab 18 in the slits I5 and applying the tape l9.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A spread sheet component comprising a sheet having a flap formed at one end foldable about a line generally parallel tosaid end, said flap having a single slit formed therein parallel to said end and the body portion of said sheet below said flap having a. single tab formed therein which is receivable and slidable in the slit of a companion component sheet, the distance of the slit to the edge of said one end of the sheet being less than the dimension of the tab taken in the same direction, whereby the tab may be inserted through the slit of a companion component sheet to extend across the sheet material located between the slit and the adjacent end edge of the component sheet.

2. A spread sheet comprising a plurality of component sheets, each having a flap at one end folded about a line generally parallel to said end, a single slit formed in said flap and a single tab formed in the body portion of said sheet adjacent said fold line, the tab of one component being inserted and slidable in the slit of another component, the slit in each component sheet being substantially longer than the dimension of the tab slidable therein taken in the same direction, the slit, in each component sheet being spaced from the edge of said one end thereof a distance less than the dimension of the tab slidable therein taken in the same direction, and an adhesive-coated tape applied to the free end of each. inserted tab and tothe body portion of its component sheet to lock the tab in its companion slit.
